Rulon
AR; light maroon
A light maroon coloured material best known as
the current version of the first Rulon introduced, namely
Rulon A. It is somewhat more flexible than Rulon LR,
hence suitable for seals and bonded coating of slide
surfaces. It has many decades of use in automotive shaft
seals and fuel metering pump cups.
Rulon
AR has a practically universal chemical inertness like
that of Rulon LR and provides long life and reliability
in continuous non-lubricated service.
Rulon LR; maroon
A maroon coloured beating material best known
for its versatile design properties. It is compatible
with most hardened steel substrates. Mild steel is acceptable;
harder running surfaces are better.
Rulon
LR has a practically universal chemical inertness. Of
the chemicals encountered in commercial practice, only
molten sodium and fluorine, at elevated temperatures
and pressures, show any signs of attack. For continuous
non-lubricated service, Rulon LR sleeve bearings are
capable of operating up to 10,000 PV. Higher values
are possible for intermittent service.
Rulon
J; dull gold
An all-polymeric reinforced, dull gold coloured
PTFE compound that operates exceptionally well against
soft mating surfaces such as 316 stainless steel, aluminium,
mild steel, brass and other plastics. The unique "shaft
friendly" material is also low in friction and
wear and is also self-lubricating.
It has one of the lowest coefficients of friction of
most reinforced PTFE materials. This makes it ideally
suited for start/stop applications where stick-slip
must be eliminated. The tribological properties of this
material also make it suitable for both bearing and
wear component applications.

Rulon 641; white
Manufactured from FDA compliant
materials which possess excellent load and wear characteristics, it offers excellent, continuous non-lubricated service
up to 10,000 PV - higher for intermittent service. While
the load capacity is generally limited
to 1,000 psi at room temperature, deformation is a function
of wall thickness, temperature and load.
Its compatibility with a wide array
of mating surfaces, including mild steel, 303 and 316
stainless steels, as well as harder materials, make
it a good choice for most food and pharmaceutical bearing
applications.
Rulon W2; black
Black PTFE-based material
developed for use in fresh-water applications. It exhibits
low friction and excellent wear characteristics (one
of the lowest wear rates in fresh water) as well as
good thermal dissipation, preventing shaft distress.
Its properties are enhanced when wet. Rulon W2 is DWGV
(European) certified for applications in contact with
drinking water.
It
is compatible with most metal substrates and soft mating
surfaces. Rulon W2 is a good alternative to Rulon J
when superior chemical resistance is needed. However,
it should not be used on very soft mating surfaces or
where electrical insulation is desired.
Rulon
123; black
A glossy black non-abrasive compound for softer
mating surfaces, such as stainless steel. This material
has excellent chemical resistance and is FDA, USDA and
NSF compliant. It is less expensive than Rulon J, but
is slightly less flexible and higher in wear.
It
has a high resistance to deformation, low coefficient
of friction and good thermal and electrostatic dissipation.
This material has a maximum operating temperature of
300°C and releases black wear debris over
time and should not be used in ultra-dry vacuum applications,
or where electrical insulation is desired.

Rulon 488; dull turquoise
Rulon
488 is a dull turquoise material originally developed
for use with painted surfaces. It has been used in veneer
dryer bearings in the plywood industry.
Its
excellent wear resistance, especially in extremely dry
environments, make it a material of choice in hydrogen
and natural gas compressors. Its almost universal chemical
resistance enables it to withstand corrosives and acids
sometimes present in trace amounts in these environments.
It
has a higher load capacity than Rulon J and better abrasion
resistance than both Rulon J and Rulon 123.
Rulon 957; speckled green
A speckled green material that was developed
specifically for noise dampening and abrasion resistance,
such as in commercial or residential clothes dryers.
It provides low friction operation on softer mating
surfaces at higher loads than Rulon J.
This
material also offers excellent performance on coated
metals, particularly porcelain. Among its many benefits
are an overall reduction of the weight of the finished
product, vibration absorption and cost reduction due
to rapid manufacturing methods.
Rulon
XL; tan
A tan coloured material that is best for use against
aluminium substrates. Exhibiting a very low wear
as compared with other Rulon grades. Other advantages
offered by this unique material are that it combines
low deformation under load with exceptionally good chemical
resistance.
It
is compatible with a wide range of mating surfaces,
but is not recommended for use with alkalis. Its non-abrasive
character enhances the frictional performance to prevent
galling of softer mating surfaces.
It
is the best material for vacuum service.

Rulon F; green
A green material with
excellent insulating properties and superior abrasion
resistance.
It is used in a wide variety of wear
component and bearing applications, and is currently
used as the liner in one of our composite journal bearings
(Rulon FCJ).
Rulon F exhibits excellent wear
resistance, especially in dry conditions. This material
suitably slides against a wide range of mating surfaces
but is not recommended for contact with strong bases
or steam.
Rulon
142; dull blue-green
Specially formulated dull blue/green
linear bearing material that exhibits low wear, high
thermal dissipation, and good dimensional stability
characteristics.
Among its many benefits are the virtual
elimination of stick-slip, vibration dampening, self-lubrication,
uniform friction, long life, ease of application and
design diversity.
Rulon
142 has excellent mechanical properties and is the ideal
material for machine tool applications. Its low deformation
characteristics limit the amount of misalignment that
can occur with other bearing materials.
Strong acids and bases should be avoided, as they may
attack the fillers.
Rulon 945; black
Black PTFE-based material that has very low
wear and deformation under load, making it ideally suited
for demanding thermal applications. In fact, its deformation
is the lowest of all Rulon grades. It also possesses
excellent chemical resistance and good dimensional stability.
It is best suited for use against hard mating surfaces,
like hardened steel substrates since it does have moderate
abrasive qualities. It is not suitable in applications
where electrically insulating properties are required.
Rulon 1045; dull gold
A dull gold material that has an excellent ability
to elongate in a flip seal application. Coupled with
excellent frictional characteristics, it offers the added benefit of energy
savings, as well as increased sealing efficiency.
This
material is also resistant to many harsh chemicals found
in the application environments where it is typically
used. It is also compatible with most commercially available
lubricants for additional reduction in friction. Its
low deformation properties allow it to be effective
as a bearing or sliding surface.

Rulon
1337; tan
A tan material made entirely from FDA compliant
components. It has excellent physical properties and
is chemically compatible with most chemicals except
concentrated sulphuric acid. This offers much flexibility
in wash-down environments of food and pharmaceutical
processing environments.
It
has a slightly lower coefficient of friction than Rulon
J, offering extended life and less abrasion with softer
mating surfaces. It is compatible with most commercially
available natural lubricants for additional reduction
in friction.
Rulon
1410; gold
A gold material with
excellent elongation and tensile strength suitable for
flip seal and other flexible sealing applications.
Coupled with low frictional characteristics, it offers
the added benefit of energy savings and/or increased
sealing efficiency.
This material is resistant to most harsh
chemicals. It is also compatible with many commercially
available lubricants for
additional reduction in torque.
It can be used as a liner material for
substrates requiring any of the above characteristics.
Rulon 1439; white
A white FDA compliant material that is suitable
for immersed service with better wear characteristics
than most other PTFE compounds. Its colour makes it
aesthetically pleasing for food and pharmaceutical applications.
This material is resistant to many harsh
chemicals found in the application environments where
it is typically used. It is compatible with most commercially
available lubricants for additional reduction in friction.
Its
properties allow it to be effectively utilized as a
bearing or sliding surface.
